(54) Fault management apparatus


(57) A fault management apparatus that enables calculation of evaluation values relating to a fault occurring to a management target as objective values without involvement of human judgment is provided. Fault information containing fault content information showing content of a fault occurring to a process in a production line, and detection status information and action content information associated with the fault is stored in a fault occurrence history storage part as a fault occurrence history. A fault extraction part reads the fault occurrence history from the fault occurrence history storage part to extract fault information containing specific fault content information. An influence degree calculation part calculates a degree of influence showing the degree of influence caused by a specific fault by performing statistical processing based on detection status information and action content information contained in the fault information extracted by the fault extraction part.
